HOLIBR-OOK W. COULTER, OF DULUTH, MINNESOTA, ASSIGNOR TO THE BETAN COMPANY, A CORPORATION OF MINNESOTA.

RADIATOR.

' Application and April 12,

To all whom it may concern Be it known that I, HOLBROOK WV. COUL- rnn, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Radiators, of which I do hereby declare the following to be a specification.

My invention relates to radiators of the water circulation type for use in automobiles, and has for its object the provision of removable circulation unit adapted to form part of a radiator and containing a heating element, whereby the water in the radiator canbe kept above the freezing point when the weather is cold and the engine dead. With these and other objects in view, it consists of the structures, combinations and arrangements of parts hereinafter described and shown. 4

In the drawings, Figure 1 is a view partly in end elevation and partly in central vertical transverse section of two removable units adapted to form part of a radiator, one of which units embodies my invention.

Fig. 2 is a top plan view of a unit embodying my invention. Fig. 3 is an end elevation of a baffle plate forming part of my invention. Fig. 4 is a reduced end elevation of a baiile plate which does not form part of my invention, but is shown for the purpose of A, more clearly distinguishing my invention from the prior art and structures with which my invention may be associated. Fig. 5 is a fragmentary side view of the plate shown in i Fig. 4:. Fig. 6 is a central vertical longitudinal section through one of said units embodying my invention. J

In the drawings, 1 is a broad and comparatively thin hollow chamber, open at one end. A bafie plate comprising a hollow shell 2, of slightly less area and thickness than said chamber is adapted to extend into said chamber, said baflle plate being provided with a shoulder 2 near its outer end for closing the end opening in said chamber, and is provided upon said shoulder with a crown portion 2 adapted to extend across the ad'acent ends of the walls of said chamber 1. n the outer surface of one of the broad walls of said chamber 1, is formed a taper bored, or female nipple 1 which communicates with the interior space of said chamber at one side of said baffle plate. On the outer surface of the other of the broad walls of said chamber Specification of Letters Patent.

1 is formed an apertured male nipple l the aperture in which is adapted to communicate with the interior space of said chamber at one side of said baflie plate. The nipples of said chamber are adapted to engage the nipples of other such chambers or modified forms thereof, to make a column of water circulation chambers, as will be readily understood. The shell 2 is preferably formed of metal, and said crown portion thereof is preferably braised on to said shoulder, but may be attached in any suitablemanner. Within said shell 2, is an insulation lining 3, preferably embodying a series of transverse insulation partitions 3 whereby the space between the side walls of said lining is divided into a series of compartments. Extending through said crown are insulation bushings l and P. Extending through said bushings are binding posts 5 and 5 of any suitable structure which posts are connected with each other at their inward ends by a wire 5 which, intermediate of its ends,

passes through or over said series of partitions and is formed into a coil within each of said compartments. The outer ends of said posts are adapted to be connected by wires 5 and 5 with any suitable source of electricity, as the generator 6.

I do not, however, claim'broadly a radiation unit comprising a broad thin hollow chamber open at one end, saidchamber having nipples formed on its sides, and a baffle plate extending into said chamber and spaced fromthe broad walls and from one of the narrower walls thereof and having a shoulder formed on one of its ends to close the open end of said chamber, because such a structure is-prior to my said invention.

In Fig. 1, of the drawings such prior chamber is shown in end elevation as at .7, and in Fig. 4 such prior baflle plate is shown on a reduced scale as at 8, said prior bafile plate being a solid plate. The main features of my present invention are the provisions of a hollow baille plate containing a heating element.

In operation, it is contemplated to use in one radiator both forms of radiation units in communication and cooperation with each other, and that preferably only one or two of the units provided with heating elements understood that if desired all the units of a radiator maybe such as contain said heating element.

W hat I claim is 1. lin a radiation unit comprising a broad thin hollow chamber open at one end, said chamber having a taper cored nipple formed upon the outer face of one of its broad Walls the bore of said nipple extending through said wall, said chamber having an apertured nipple formed upon the outer face of the other of its broad walls, said aperture extending through said wall, a hollow baffle plate extending into said chamber, said baille plate being spaced from the broad walls and from one of the narrow walls of said chamber, said baille plate having a shoulder formed thereon to close the open end of said chamber, an insulating lining within said baiiie plate, wire-binding posts mounted in said plate and extending outwardly therefrom means for insulating said posts from said plate, and a Wire entending between the lining walls of said plate and connecting the inward ends of said posts with each other.

2. A broad thin chamber adapted to conduct water said chamber having a receiving port at one side and a discharge port at the opposite side, a hollow baffle plate positioned in said chamber and spaced from the broad sides and from one of the ends thereof, a lining of insulating material within said baffle plate, an electric heating coil between the walls of said lining, pole pieces connected to said coil and extending outwardly of said water chamber, and means for insulating said pole pieces from said chamber.
